ABSTRACT:
A process for the preparation of an organ-specific substance labeled with technetium-99m
The invention relates to a process for the preparation of an organ-specific substance labeled with technetium-99m, in which no unwanted Tc-99m compounds are bound to the antibody. This is achieved by using the complexing agent required for the reducing agent in an amount which is stoichiometric relative to the reducing agent.
